Radiographic examination of the small bowel: survey of practice patterns in the United States.

Purpose: To obtain understanding of the current practice patterns of academic and private radiology groups in the United States in radiographic examination of the small bowel.

Materials And Methods: The survey consisted of questions about small-bowel follow-through (SBFT) examinations, including frequency of overhead radiographs, use of fluoroscopic spot images, personnel performing fluoroscopy, practice settings, and degree of specialization. By using a standard sampling technique, the country was divided into nine regions, and one state from each region was randomly selected.

Evaluation of patients with jejunostomy tubes: imaging findings.

Purpose: To determine the frequency and nature of abnormalities observed on radiographs after placement of jejunostomy (J) tubes for enteral nutrition.

Materials And Methods: Radiology database review revealed that 280 studies of the J tube or of the small bowel with water-soluble contrast material and/or barium sulfate were performed in patients during 10 years. Review of the radiologic reports revealed abnormalities related to the placement of tubes in 105 (38%) cases.

Value of barium studies for predicting primary versus secondary non-Hodgkin's gastrointestinal lymphoma.

Background: To determine the predictive value of a single lesion versus multifocal disease for differentiating primary and secondary gastrointestinal (GI) lymphoma on barium studies.

Methods: Our study group consisted of 90 cases of non-Hodgkin's GI lymphoma from the radiologic archives of the Armed Forces Institute of Pathology in which barium studies had been performed. Each of those studies was reviewed jointly by two of the authors to determine in a blinded fashion whether the patients had a single lesion or multifocal disease (defined as two or more discrete lesions).

Diagnosis of colorectal neoplasms at double-contrast barium enema examination.

The double-contrast barium enema examination has been recognized as an option for colorectal cancer screening in Americans with average risk who are greater than 50 years of age. The purpose of this article is to review the principles for diagnosing colorectal neoplasms on double-contrast images and the spectrum of findings associated with these lesions. Colonic polyps can be sessile or pedunculated; their appearance depends on whether they are located on the dependent or nondependent wall of the bowel.
